What's your fuel pressure?  I've seen this problem on GM's with a bad
CTS.  The sensor was going Hi-Z in the motor, but not when out.  I replaced
the 15 dollar sensor and all was good.

This is an 83, is this a CFI car?  EEC-III?

Those who would give up essential liberty to purchase a little temporary safety
deserve neither liberty or safety. Nor, are they likely to end up with either.
